\"\"<\/a><\/p>\n

In December 2023 (I think) a new thin watch was launched, 9% thicker, 8% wider and with 21% larger display than the T8<\/a>.<\/p>\n

I got it 2024-02-27. The verdict is: Disappointment<\/strong>!<\/p>\n

Lastest updates: 2024-03-09, back in box!, 2024-03-28 References to T8 Mini<\/a>, 2024-11-12 DA09<\/a> better in all areas!<\/p>\n

<\/p>\n

It is not a successor of the T8, I believe it is another company “Funost Tech” (YouTube channel here<\/a>), and the TN88 looks more like a classic watch, especially the band arms, for the standard pin 20mm bands. Though it do use identical charging distance and ‘polarity’.<\/p>\n

I have been quite pleased with the T8 and bought many, so you might start with browsing the TL;DR part of that review<\/a>.<\/p>\n

The only monitoring the TN88 and T8 Mini offers are sleep, steps and heart rate.<\/p>\n

I was pleasantly surprised that it despite the substantially larger size and the use of steel, it’s slightly lighter<\/em> ~0.65g (or ~2.4%) . But it does not feel like tin-can thickness.<\/p>\n

The 304 vs 316 steel means less Nickel and less risk of reaction, I had a slight irritation, but not enough to the skin got red. Just a light ‘burning’ feeling, mainly by the band, so the case could be ok.<\/p>\n

Stainless steel 316 contains about 10% nickel, so should<\/em> be hypoallergenic<\/em><\/a>.\u00a0 If I get a rash that alone would have killed any enthusiasm left over the TN88 quickly…<\/p>\n

Many listings have features in images, and not as text, I found a list here<\/a>
\nCalendar, Alarm Clock, Remote Control, Sleep Tracker, Fitness Tracker, Passometer, Call Reminder, Answer Call, Push Message, Message Reminder, Dial Call, Heart Rate Tracker, Activity Tracker, Heart Rate Monitor, Breath Monitor<\/del>, Music player, Sedentary Reminder, AI voice assistant<\/em><\/p>\n

I stroke out the one that isn’t there…<\/p>\n

(On the battery 200mAh is printed on the box)<\/p>\n

 <\/p>\n

Variants<\/h2>\n

The case exists in three variants gilded<\/em>, steel with gilded ring<\/em> and steel<\/em>. (The last two offered with a number af bands out of the box, that you obviously can replace at will, as it is std. 22mm pin bands)<\/p>\n

\"\"<\/a>\"\"<\/a> \"\"<\/a><\/p>\n

I ordered it here<\/a>, for \u20ac28 including shipping (\u20ac35 also including local Danish taxes), the other I ordered from another seller a bit more expensive to get it quicker, and that is the one I got first, though not quite the variant I ordered.<\/p>\n

 <\/p>\n

Before ordering I considered this variant I found looking very appealing, with integrating band ends, butterfly clasp and everything<\/p>\n

\"\"<\/a><\/p>\n

(I only found that variant for sale here<\/a> at a shop with about double prices on all, but offers a wide number of variants!)
\nBut on second thought I reflected that it might look fairly ugly when the display is off, as faked here:<\/p>\n

\"\"<\/a><\/p>\n

Had it been black with the same golden ornaments, I think it might have looked really nice. Tried to fake that somewhat with simple inversion tools (all plus hue). Though it ended more gun metal than black….
\n\"\"<\/a>\"\"<\/a><\/p>\n

 <\/p>\n

I found this video<\/a>, in the Funost channel and I noticed that the TN88, unfortunately have the glass sticking out <\/strong>slightly (though very little), increasing the risk of scratches if you have it upside down, e.g. for charging, so the display will get any ‘beating’ from sharp dust on a table. e.g. ash. Sort of defeating the purpose of using a steel case… But of course this is normal for proper watches too, so helps in making it look more like a real watch, so pros and cons….<\/p>\n

\"\"<\/a><\/p>\n

In contrast the T8 got the metal sides a hair over the glass, reducing the risk of scratches.<\/p>\n

 <\/p>\n

Protrusions and holes<\/h2>\n

The sensor protrusion is an about 24mm wide round island with slanted edges (from images about 20s into the above video, including the below).
\nAn oddity I have not seen before is that the charging contacts got a small protrusion island too, of about 15\u00d76mm, and about half the height. I bet this was added with the sole purpose of claiming the thing as a bit thinner. Seems a bit silly, but maybe it was to just to get the bragging rights over the T8?. You do not notice any tilt by this on the arm. But combines with the about 50% larger protrusion the Tn88 does not\u00a0 ‘sink into’ the arm (as the T8 do), and thus have the watch hoovering slightly. Though it is not as bad as e.g. the E600<\/a>, easily catching a shirt sleeve.<\/span><\/p>\n

\"\"<\/a><\/p>\n

Note also the two small round holes and a slit on the back. The slit is the speaker, and at the least one of the round holes is a mic. It is a rather weird that you have to take it off for using the mic\/speaker, and you really can not hear the alarm when it goes off on the arm. You can not select to turn the alarm sound off, though it does have a (weak) vibrator also. If your arm is so thin that it starts curving well before the speaker-slit (and this watch thus grossly\u00a0 oversized), the sound might work though…
\nIt might be argued that the holes sits fairly protected during normal wear, but a thin argument for a very weird placement. I think it would have been much better if they had been placed at the case ‘ends’, so they were protected by the band attachments, and not blocked by the arm.
\nADD:<\/strong> The thinner T8 Pro<\/a> has placed the speaker and the mic exactly like suggested…<\/em>
\n(Do not get fooled by the the image above on the side opposite the crown. These are just reflections, not<\/em> speaker holes)<\/span><\/p>\n

This video<\/a> looks like pure rendering (with exaggerated display size), but have nice clear details. (e.g. the holes)<\/p>\n
